CLAMP.

Specification of Letters Patent.

Patented Oct. 19, 1920.

To all whom it may concern I Be it known that I, SEBASTIAN GAUL, a

citizen of Bavaria, residing at New York, .in the county and State of New York, have clamp of very simple and inexpensive construction which is easily adjustable to fit different thicknesses of boards as well as various numbers and widths of boards.

The invention will'be first hereinafter described in connection with the accompanying drawings, which constitute part of this specification, and then more specifically defined in the claims at the end of the description.

In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views Figure 1 is a plan view of a clamp construction substantially in accordance with this invention shown holding four boards.

Fig. 2 is a side view of the clamp as shown in Fig. 1, the boards being in section.

Fig. 3 is a view similar to Fig. 2 but showing the clamp adjusted to fit a different 7 thickness of boards.

Fig. 4 is a section on the line IV-IV of Fig. 2, showing the adjustable connecting device in elevation.

Fig. 5 is a section on the line VV of the same figure.

Figs. 6 and 7 are sections on the lines VIVI and VII-VII of Fig. '3, and

Fig. 8 is a detailed View of the adjustable connecting piece which carries the screw clamping member.

The clamp consists of two similar bars or strips 1 preferably made of metal and formed with staggered holes 2 extending throughout the greater portions of their lengths, and a pair of openings 3 arranged side by side and in line with the two rows,

of holes 2 respectively but in one end'portion of said bars. These bars may be adjustably connected together by means of two spider shaped members 4 and 5. The connecting member 4 has a straight angular body portion 6 with round or cylindrical lugs 7 projecting from its ends and other similar lugs 8 projecting in opposite directions from its sides. Either pair of lugs 7 or 8 may be inserted in any of the holes 2 in the bars 1' for connecting said bars together and providing an abutment for the boards at one end of the clamp.

The connecting member 5 also has a straight angular body portion 9 with oppositely projecting oval lugs 10 at its ends and other similar lugs 11 at its sides. Said lugs 10 and 11 are adapted to fit in the openings 3 which are shaped to correspond. Through the central portion of the body 9 a screw threaded passage 12 isformed in which a screw clamping member 13 is engaged. One end of said clamping screw 13 is swiveled to a bearing block 14 adapted to bear against the boards to be clamped, while the other end of said screw is squared, as at 15, to receive a crank 16 or other suitable operating or turning device.

As illustrated in Figs. 2, 4 and 5, the lugs 8 of the connecting device 4 may be engaged with any of the holes 2 in the bars 1 so as to adjust said bars close together for fitting narrow boards 17, and the lugs 11 of the connecting member 9 may be engaged with the opening 3 which is in line with the holes 2 engaged by the member 4. As shown in Figs. 3, 6 and 7, the lugs 7 of the member 4 and lugs 10 of the member 9 may also be engaged with holes 2 and openings 3, respectively, for adjusting the clamp to fit boards 18 ofgreater thickness. It will be noted that the dimensions of the connecting members 4 and 5 may be changed so as to provide any two basic adjustments desired, and by engaging the lugs into the holes and openings 2 and 3 to various depths a wider range of adjustments may be had.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. In a clamp of the character described, the combination with a pair of bars having perforations therein, of connecting devices adapted to be engaged with different ones of the perforations in said bars to accommodate boards of different widths,the same connecting pieces being adjustable to space the bars at different distances apart for accommodating boards of different thicknesses.

extending lugs for engaging the sockets in the bars and spacing them at different dis tances apart to accommodate boards of different thicknesses.

3. In a clamp of the character described, the combination With a pair of bars having sockets therein, of connecting devices each having a plurality of pairs of oppositely extending lugs to fit said sockets in the bars,

the lugs of each pair being arranged at different distances apart for spacing the bars to accommodate boards of different thicknesses.

In a clamp of the character described, the combination With a pair of bars having sockets therein, of connecting devices each having a plurality of pairs of oppositely extending lugs to fit said sockets in the bars,

7 the lugs of each pair being arranged at difing devices and adapted to clamp the boards.

between said screw and the other connect- 25 ing device.

In testimony whereof I have name to this specification.

SEBASTIAN GAUL.
